I have always wished I knew something more about electronics. The wife and I have lived on our Passport 45 Ketch, S/V Katie Lee most of these past 17 years. Hobbies have to be small, an since we are 'subsistence living', inexpensive. Ha!

More NMEA Bridge modules

I finally got around to testing the last 2 WiFi Bridge boards. Neither worked at first. I wasn't sure of anything.

I chose one board and went through the entire regression. When I finally got the scope (Xprotolab) out and followed the NMEA signal in, I found a broken trace. The input to the first resistor. Arg! Then I discovered I put the transistor in backwards in both boards.

But now they are both installed and broadcasting. The first is connected to the builtin Garmin GPS and depth finder data, wire-or'd on the same terminal strip at 4800 baud. And the second is connected to the AIS at 38400 baud.

Then I etched two more boards, but haven't drilled or populated them yet.
